Abstract:
The invention resides in a module (2) used in conjunction with other such modules in an apparatus for rapidly producing an article having a three-dimensional design comprising a base (1), a plurality of pins (5) movable relative thereto, a plurality of drive motors (14) corresponding, in number to the number of said plurality of pins and means interconnecting each of said plurality of pins with said base, each said means being connected independently between said base and a corresponding one of said pins. A control means (22) interconnects each of said drive means (14) and a controller (20) with one another to effect selective energization of said drive means.
Abstract:
A method and apparatus is disclosed for "intelligent" control (410) of production processes such as machining, casting, heat treating and welding. The key enabler of such control is of an electro-optical (25, 95, 305, 405) or other suitable sensor type. The sensor is generally of non contact type, capable of rapidly and accurately acquiring data from parts and the tools used to produce the parts in a production "in-process" environment. Systems are disclosed to control not only the instant operation, but those processes connected therewith, both upstream and downstream. Data bases are generated and knowledge bases are used. Application of the invention can improve quality and productivity, and allow the production of parts which have unusual or individual material characteristics (1000-1008).

Abstract:
Described herein are systems and methods for creating a custom registration guide. In general, the methods may include receiving scan data of a patient's bone; creating instructions based on the scan data for creating a three-dimensional surface model of the patient's bone; and moving a plurality of moveable elements, coupled to the adjustable model, based on the instructions. The method may further include the steps of placing a malleable registration guide onto the adjustable model and shaping the registration guide to fit to the adjustable model. The method may further include the step of intraoperatively determining the location of a patient's bone using the custom registration guide. The step of determining the location of the patient's bone may include the steps of coupling the registration guide and fiducial markers to the patient's bone.

Abstract:
This invention details a computer controlled self adjusting sheet metal forming die (10) which can provide rapid contour changes. It eliminates the need to manufacture, store, and change individual forming dies for forming different contours, and comprises a computer control device (100) which sends appropriately timed signals to translate each contour element so that a three dimension surface is formed by a discrete matrix of individual pins (15). This self adjusting sheet metal forming die is used on a sheet metal press wherein sheet metal can be formed by pressing or stretch forming the metal against the contoured surface.

Abstract:
A method for the rapid preparation of patterns, molds, dies or forms, consists of a CAD/CAM system (including a postprocessor) in which is modeled the three-dimensional object for which the imprint is to be prepared, a robot with controller and tool bit or end effector, and one or more matrices each containing an array of slidable pins or rods. By displacing the pin/rod elements along their axis by determined amounts according to the shape of the object for which the imprint is being prepared, a pattern or mold or die or form is obtained for producing the three-dimensional object.
Abstract:
A method for regulating a device (2) used for fixing aircraft airframe pieces in connection with assembly of airframe parts (21, 22), where the device consists of a rig (3) comprising a matrix of rails (7, 8) that can slide in such a way that a number of fixing elements (9) attached to the rails (7, 8) can be positioned freely along three co-ordinates x, y, z in space within a given volume, where a manipulator (1) grasps a fixing element (9) after which the fixing element (9) is moved by the manipulator (1) to the given co-ordinate, and where the rails on which a fixing element (9) is arranged is locked in relation to the rig (3) by an automatic locking function initiated by the manipulator, thereby fixing the fixing element's (9) position in space and the setting procedure is repeated for a predetermined number of fixing elements (9) on the rig.
